Rated 5 out of 5 by from Like a hot knife in butter. As a timber farmer here in the PNW, I have been running saws for almost 30 years, and this is the best Stihl that I have ever used. My old 066 used to vibrate so much that after 4 hours of use I could not feel my hands. No more. This saw has a very much improved isolation system and even more power. My dealer told me to be careful with its fuel, and I have not had it long enough to comment. But I bought the Stihl canned gas just in case I give the chainsaw work a break for a few months. Want the best? Spend the money and get this saw.

Rated 5 out of 5 by from Good stuff yeye Ime a full time chaser on a thinning yarder, i bought this saw for personal use and use at work when only tree length comes to the landing. We got no processor or dansco and i buck 100+ foot logs with this saw. It starts everytime and doesnt even need the choke if you wanna rip on it a few extra times. My 661 gets tossed, thrown, and stepped on and packed with mud and gets wet all the time and still runs better than the lil 461's. I highly recomend it but ONLY run clear gass mix with stihl's brand of mixing oil otherwise you do get the same problems as all these other guys who blow up somthing too big for their balls

Rated 2 out of 5 by from This product needs a factory revision Starts hard when it is warm. We use it to cut logs on the landing and when you run it hard it will stall and not start up again. Sometimes you have to wait over half an hour for it to start again.

Rated 2 out of 5 by from This saw has intermittent problems and issues Saw works good most of the time but it stalls out sometimes and is hard starting and eventually after four months blows up. This is after a professional break-in, using stihls synthetic mix with 91 ethanol free fuel only. Took it back to the dealer can I find out why it failed. The only possibility they told me was it could've been from dust ingestion from the dirty filter

Rated 4 out of 5 by from Great power out of this saw but... I love the power and features however it cottons to have hot start issues which I've been hearing about a lot more. I will love this saw more if it gets fixed correctly...

Rated 1 out of 5 by from This saw has descent features but is absolutely unreliable i have 2 and they blow up every 50 hours of use completely unacceptable Have had nothing but problems with 661 blow up every 60 to 80 hours

Rated 5 out of 5 by from The F1 of Stihl saws I'm a timber cutting contractor. I've been cutting for nearly 40 years. I run a saw 7 hours per day. I've owned over 50 Stihl pro saws. I have never been so impressed with a new saw as I am with this one. The one major change over the 660 is the automatic carb. I thought I would hate it but I absolutely love it. Starts easy and runs perfect. The multi switch is great- it always springs back to the run position. Super handy. The bar nuts are attached to the clutch cover- try losing one of those! The starter/fan cover is flatter and consequently MUCH easier to sight with. It also has a sight that runs parallel to the bar when you're getting down to the last of your holding wood. Brilliant! The air filter lasts all day even here in California's dry Sierra bark dust. Spring anti vibe is definitely smoother than rubber. Muffler is quiet. Love the "can't lose 'em" fuel and oil cap. Super torque but revs like an F1 racer. And to top it all off, it burns about 20% less fuel than the 660! We still have some pretty big wood here in CA (I get at least one 5' every week) and this saw was made for what I do. Love it!
